How to Use the Azure Cognitive Search MCP in LlamaIndex

Q: How do I configure Azure Cognitive Search in LlamaIndex?

Run pip install llama-index-tools-mcp first. Initialize a BasicMCPClient with your Vinkius endpoint, then wrap it in McpToolSpec. Call await mcptoolspec.totoollistasync() to pass the tools to your FunctionAgent.

Q: How do I restrict which Azure Cognitive Search MCP Server tools LlamaIndex uses?

Use the allowedtools parameter when creating your tool spec. You can allow vectorsearch while blocking listindexers. This keeps your RAG agent focused strictly on data retrieval.

Ingest Azure Cognitive Search data directly into your LlamaIndex RAG pipelines.

Perplexity

Index MCP Server queries into local stores

The `list_indexes` tool pulls your entire Azure Search topology into LlamaIndex. Your application maps remote index schemas and caches them locally for faster semantic routing. Agents know exactly which remote index holds the right data before firing a query. Responses from the MCP Server become part of your searchable knowledge base. When you pull index details using `get_index`, LlamaIndex embeds that metadata. Future agent queries about your infrastructure rely on actual API data instead of guessing.

Ground RAG apps with exact documents

The `get_document` tool retrieves specific records by their UUID key for direct ingestion. LlamaIndex takes that exact JSON payload, chunks it, and adds it to your active vector store. Bridging the gap between remote Azure storage and your local RAG application happens instantly. You filter which tools the agent can access. By passing an `allowed_tools` array to the `McpToolSpec`, developers restrict the agent to read-only document fetches. The system stays focused on building the knowledge base without wandering into administrative endpoints.

Combine KNN vectors with semantic search

The `vector_search` tool executes structural KNN queries against your Azure embedding profiles. LlamaIndex treats these remote vector hits just like local document retrievals. Merging results from Azure with local PDF embeddings creates a single, unified response. Setting `include_resources=True` allows the framework to pull raw data alongside the tool execution. The agent synthesizes answers using both the vector distances and the actual text payloads. Highly accurate responses grounded in multiple retrieval methods are the direct outcome.

Setup guide

Set up Azure Cognitive Search MCP in LlamaIndex

Prerequisites

Python 3.10+ installed
llama-index-tools-mcp package
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install llama-index-tools-mcp llama-index-llms-openai. The MCP tools package provides BasicMCPClient and McpToolSpec.
2

Connect with BasicMCPClient
Point BasicMCPClient to your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports SSE and Streamable HTTP transports.
3

Convert to LlamaIndex tools
Call mcp_tool_spec.to_tool_list_async() to convert all Azure Cognitive Search MCP tools into native FunctionTool objects that any LlamaIndex agent can use.
4

Run with any LLM
Create a FunctionAgent with the tools and your preferred LLM. Swap OpenAI for Anthropic, Gemini, or any LlamaIndex-supported provider.

agent.py

from llama_index.tools.mcp import BasicMCPClient, McpToolSpec
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

# Connect to the MCP
mcp_client = BasicMCPClient(
    "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
)
mcp_tool_spec = McpToolSpec(client=mcp_client)

# Convert MCP tools to LlamaIndex tools
tools = await mcp_tool_spec.to_tool_list_async()

# Create and run the agent
agent = FunctionAgent(
    tools=tools,
    llm=OpenAI(model="gpt-4o"),
    system_prompt="You have access to Azure Cognitive Search tools.",
)
response = await agent.run("List recent Azure Cognitive Search data")

Common questions about Azure Cognitive Search MCP in LlamaIndex

Run `pip install llama-index-tools-mcp` first. Initialize a `BasicMCPClient` with your Vinkius endpoint, then wrap it in `McpToolSpec`. Call `await mcp_tool_spec.to_tool_list_async()` to pass the tools to your `FunctionAgent`.

The framework naturally indexes tool outputs into its own vector stores. When an agent runs `search_documents`, the returned text gets embedded locally. Subsequent queries hit the local cache instead of reaching out to Azure.

Use the `allowed_tools` parameter when creating your tool spec. You can allow `vector_search` while blocking `list_indexers`. This keeps your RAG agent focused strictly on data retrieval.

Yes, the client handles asynchronous requests natively. You build concurrent data ingestion pipelines that query multiple Azure indexes at once. The agent waits for all promises to resolve before synthesizing the final answer.

The server reads your Azure Search indexes, scheduled indexers, and exact document UUIDs. Vinkius isolates this activity within an ephemeral zero-trust sandbox. No data persists on our infrastructure after LlamaIndex closes the connection.
